A weak ridge of high pressure will bring a spell of relatively benign conditions to S Scotland and into England and Wales. However, showers will affect NW Scotland and there is uncertainty in the extent that strong winds, rain and low cloud clear from the NW across Wales.
Upland gales or near gales easing slowly. Rain soon easing to isolated showers.
Southwesterly 35 to 40mph. Will tend to ease a little though the day.
Walking arduous and wind chill significant on higher areas.
A few showers
Overnight rain clearing at or soon after dawn. Through the day, scattered showers, mainly west of A9, hail or above 800m snow - only flurries Cairngorms NP.
Extensive on higher areas
Cloud base will vary, generally lowest Ben Alder and southern Cairngorms NP, where typically 600m near precipitation and otherwise 900m. Elsewhere, cloud rare below 700m, and most cloud above 1100m.
30% west of A9 to 70% summits accessible from Deeside
Occasional sunshine, particularly lower slopes Cairngorms and Deeside. Varying visibility; sometimes very good, but abruptly poor in precipitation.

Low confidence in this forecast: Southerly 50 to 70mph morning and 30 to 45mph afternoon.
Walking, or any mobility, may be very difficult on higher areas, and wind chill severe. Sudden powerful gusts even lower slopes.
Widespread rain
Deteriorating, perhaps soon after dawn, as widespread rain, preceded over a couple of hour by snow above 800m, spreads northwards. Likely to improve to showers again in the afternoon.
Generally extensive
There may be breaks to 1100m temporarily. In rain cloud will form extensively at 500m from Ben Alder east to summits north of Glen Garry and 700 to 900m further north.
20%
Little or no sunshine. Visibility be be excellent temporarily, but in rain will become poor.
2C rising to 6C
Above the summits for several hours but 1000 to 1200m post dawn and again by dusk.

South veering southwesterly 45 to 65mph.
Mobility difficult for periods and wind chill severe where exposed on higher areas.
Frequent rain
Intermittently dry, but overall, rain on and off. Most rain west of A9 and summits accessible north of Glen Garry, where very wet underfoot, burns and rivers in spate.
Extensive on higher areas
A few breaks to higher tops, but overall the Munros cloud covered. Typical cloud base 500-700m west of A9 and summits accessible north of Glen Garry, rising to 750-1050m N Cairngorms and Deeside.
30%
Rare patches of sun, most likely lower slopes Cairngorms NP. intermittently misty and at times very poor visibility.
2C
Intermittently above the summits, but at first and again later in the day, 1050m.
A series of deep Atlantic lows and their associated bands of rain and severe gale or storm force upland winds will affect Britain until early next week. It will then turn much drier, although some uncertainty as weak fronts may still affect northwest Scotland.
